Horner’s Syndrome

Horner’s Syndrome affects the nerves that run to the eye and face. When nerve fibers are interrupted, it causes the Horner’s syndrome that begins in the hypothalamus and spreads to the face. Extreme nerve fiber injuries are mostly caused by injuries to carotid artery and to the brachial plexus (neck nerves), migraine, stroke, brain tumor, or tumor at the top of the lung. Occasionally does Horner syndrome occurs at birth time (congenital condition). It may also appear with pigmentation of the colored part of the eye, called iris. Common symptoms include reduced sweating on the affected face area, drooping eyelid, sinking of the eyeball, and a small or constricted pupil.
